CAR-REPLACER.

SPECIFICATION forming part of Letters Patent No. 750,896, dated February2, 1904.

Application filed July 11, 1903. Serial No. 165,149. (No model.)

To all whom, it may concern:

Be it known that I, EMIL W. ROSEN'BERG, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Replacers, ofwhich'the following is a specification.

This invention relates to improvements in frogs for replacing derailedcars and engines on the rails; and its object is to simplify and improvethe construction of replacer-frogs so that they can be manufactured atless expense than heretofore and used with more satisfactory results.

A further object of the invention is to provide frogs which are adaptedfor any size of rail and which can be used for replacing cars or enginesin either direction and from either side of the rail.

IVith these and other ends in view the invention consists of the novelconstruction of the frogs illustrated in the accompanying drawings, inwhichi Figure 1 is a perspective view illustrating the use of myinvention and showing a pair of wheels in full lines about to mount thefrogs and in broken lines sliding from the frogs to the rails. Figs. 2,3, and 4 are perspective views of the frogs. Figs. 5 and 6 arecross-sectional views on the lines 5 5 and 6 6 of Fig. 2.

In the drawings like numerals of reference designate corresponding partsin the several figures, and referring thereto A is the frog which isadapted to be used on the outside of the rail, and B is the frog whichis adapted to be used on the inside of the rail. These frogs areconstructed substantially alike, except that A is higher at its high endthan B to lift the flange of the wheel overl the rail.

Each frog is wedge-shaped-that is to say, is in the form of anacute-angled triangular prism both longitudinally and transversely,being higher at one end 10 and at one side 1l than at its other end 12and side 13. The top 14 and bottom 15 are substantially fiat and areinclined toward each other longitudinally and transversely of the frogfrom the wide end 10 to the narrow end 12 and from the wide side 11 tothe narrow side 13. The construction is such that when the frog isresting on one face 14: or 15 it will have an even and fiat bearingthroughout the major portion of the face and at each corner of thenarrow end thereof, and the upper face, which is to receive the wheel,is inclined toward the rail to cause the wheel to slide toward and ontothe rail as it rides up to the high end.

For the purpose of firmly securing the frog in position I provideflanges 16, which are adapted to take into the ties, and in order thatthe position of the frog with relation to the rail may be constantlymaintained I provide projecting lugs 17 on the narrow side of Vthe frogto rest upon the flange of the rail, so

that the rail will support the inner side of the frog should the tiessink under the weight of the car or engine.

These frogs are preferably made in the form of shells and suitablybraced, and they are simple in construction, free from movable or comiplicated parts, and comparatively inexpensive to manufacture. Theycan beused to replace a car or engine in either direction of the track andfrom either side of the rails, and of course they can be. secured inposition on the ties to replace the car or engine from any reasonableangle to the rails. For the purpose of enabling the wheels to mount thefrogs more readily I prefer to cut out the faces of the narrow end ofeach frog at 18 between the corners, which provide a rm and substantialbearing for this end of the frog.

As these frogs can bevused reversibly, it is apparent that they needonly be made of a length for use in replacing cars or engines in onedirection, and the simplicity of construction enables the frogs to bemade very strong without increasing their weight or adding to theexpense of manufacture. The Wedge shape ofthe frogs enables the car orengine to mount them easily, and as the wheels move up to the wide endthey will naturally slide down the inclined faces toward and onto therails.

\ Without limiting myself to the exact construction and arrangement ofparts herein shown and described, what I claim, and desire 4.
